What is Wireless LAN?
Wireless LocalArea Network (WLAN) systems offer a great number of advantages over
traditional wired systems. WLAN is flexible and easy to setup and manage.
Using radio frequency (RF) technology, a WLAN transmits and receives data through the air.A
WLAN combines data connectivity with user mobility. For example, users can roam from a
conference room to their office without being disconnected from the network.
Using WLAN, users can conveniently access-shared information, and network administrators
can configure and augment networks without installing or moving network cables.
WLAN technology provides users with many convenient and cost saving features:
Mobility: WLAN provide LAN users with access to real-time
information anywhere in their organization, providing service
opportunities that are impossible with wired networks.
Ease of Installation: Installing is easy for novice and expert users alike,
eliminating the need to install network cables in walls and
ceilings.
Scalability: WLAN can be configured in a variety of topologies to adapt
to specific applications and installations. Configurations are
easily changed and range from peer-to-peer networks suitable
for a small number of users to full infrastructure networks of
thousands of users roaming over a broad area.

Wireless LAN Modes
Wireless LANs can be configured in one of two ways:
Ad-hoc Networking
Also known as a peer-to-peer network, an ad-hoc network is one that allows all workstations
and computers in the network to act as servers to all other users on the network.
Users on the network can share files, print to a shared printer, and access the Internet with a
shared modem. However, with ad-hoc networking, users can only communicate with other
wireless LAN computers that are in the same wireless LAN workgroup, and are within range.
Infrastructure Networking
Infrastructure networking differs from ad-hoc networking in that it includes an access point.
Unlike the ad-hoc structure where users on the LAN contend the shared bandwidth, on an
infrastructure network, the access point can manage the bandwidth to maximize its utilization.
Additionally, the access point enables users on a wireless LAN to access an existing wired
network, allowing wireless users to take advantage of the wired networks resources, such as
Internet, email, file transfer, and printer sharing.

Page 8 NP5420 11G Wireless PC Card User Guide
Infrastructure networking has the following advantages over ad-hoc networking:
Extended range: Each wireless LAN computer within the range of the
access point can communicate with other wireless
LAN computers within range of the access point.
Roaming: The access point enables a wireless LAN computer
to move through a building and still be connected to
the LAN.
Wired to wireless LAN connectivity: The access point bridges the gap between wireless
LANs and their wired counterparts.
Notes on Wireless LAN Configuration
When configuring a wireless LAN (WLAN), be sure to note the following points:
■Optimize the performance of the WLAN by ensuring that the distance between access
points is not too far. In most buildings, WLAN Adapters operate within a range of 10 ~ 30
metres, depending on the thickness and structure of the walls.
■Radio waves can pass through walls and glass but not metal. If there is interference in
transmitting through a wall, it may be that the wall has reinforcing metal in its structure.
Install another access point to circumvent this problem or try moving your existing access
point.
■Floors usually have metal girders and metal reinforcing struts that interfere with WLAN
transmission. It is recommended that you use at least one access point for each level of your
building.
